Using the Multi-Task Message Feature for Version 8.0

Introduction

Illustrations used in this article are from OnePager Pro using data from Microsoft Project but the features, function, controls, and manual edits apply equally to other OnePager editions that import from data sources like Microsoft Excel, Microsoft Planner, Smartsheet, Oracle Primavera P6, Planisware Enterprise, Asana, and Wrike.

This article provides details about using the Multi-Task Message Tool. This tool allow you to quickly make calculations in the chart area for durations, early start dates, and late finish dates between selected task bars/milestones symbols. The calculations can be made in the chart area by selecting the calculation tool needed from the dropdown list in the Chart Properties form’s Advanced tab’s Display options control group as shown in the illustration below for the Chart Properties form:

Once the desired calculation tool is selected, you can make task bar/milestone symbol selections in the chart area and OnePager automatically displays the results in the lower right corner of The Chart called the .

The Multi-task Message tool uses Start and Finish dates specified in the Chart Properties form’s Field Mappings tab’s Date Mappings control group’s Start and Finish dropdown lists as shown below:

By changing the Start and Finish date selections in the two dropdown lists shown above you can gain additional visibility into durations, early Start dates, and late Finish dates found in the chart area for a large variety of date fields imported from any source plan supported by OnePager.

Option Definitions

The eight (8) Multi-task message tool options are described in the list below:

1) Total Elapsed Duration: The Total Elapsed Duration option tool calculates the difference between the Finish Date of the later task selected and the Start Date of the earlier task selected. The calculated number of days displayed in the Status Bar excludes weekends (Saturdays and Sundays).

2) Total Scheduled Duration: The Total Scheduled Duration option tool calculates the sum of all durations of all selected task bars/milestone symbols. Multiple task bars/milestone symbols can be selected in the chart area. The calculated number of days displayed in the Status Bar excludes weekends (Saturdays and Sundays).

3) Earliest Start Date: The Earliest Start Date option tool finds the earliest Start Date among the Start Dates for all selected task bars/milestone symbols. Multiple task bars/milestone symbols can be selected in the chart area.

4) Latest Finish Date: The Latest Finish Date option tool finds the latest Finish Date among the Finish Dates for all selected task bars/milestone symbols. Multiple task bars/milestone symbols can be selected in the chart area.

5) Start Date of Later Task Minus Finish Date of Earlier Task (Select only two): This tool calculates the difference between the Start Date of the later task and the Finish Date of the earlier task. This tool is restricted to the selection of two task bars/milestone symbols by the nature of the calculation. The calculated number of days displayed in the Status Bar excludes weekends (Saturdays and Sundays).

6) Start Date of Later Task Minus Start Date of Earlier Task (Select only two): This tool calculates the difference between the Start Date of the later task and the Start Date of the earlier task.

Using the Multi-Task Message Tool

The Multi-task Message Tool is available for use with any OnePager Chart where OnePager imports Start and Finish date information from your source plan. The Start and Finish dates used by the Multi-task Message tool are based on the selections made in the Chart Properties form’s Field Mappings tab’s Date Mappings control group’s Start and Finish dropdown list windows. In all the examples used in this article, the Microsoft Project Start and Finish dates are used.

For these examples, the Microsoft Project source plan below shows three sets of task bars:

The first set of four task bars start and finish during the normal five day work week.

The second set of four task bars are seven days in duration and start and finish during weekend days.

Finally, the third set of four task bars are fourteen days in duration, start and finish within a normal five day work week, but span one weekend each.

The Microsoft Project source plan looks like this:

When OnePager Pro is used to create the OnePager Chart, it looks like this:

Red vertical curtains are added in The Chart above to show the weekend days.

As mentioned above the default setting for the Multi-task Message Tool is Total Elapsed Duration and this option is available immediately upon creating a Chart. To engage the tool, you only need to select one or more task bar/milestone symbols in the chart area and the tool provides the duration calculation in the Status Bar located at the bottom right corner of the Chart Editor window as shown in this illustration:

In the illustration above the four top task bars are selected and automatically the Multi-task Message Tool displays the Total Elapsed Duration of 19.4 days in the Status Bar in the bottom right corner of the Chart Editor window.

Multi-Task Message Tool Examples

This sub-section contains examples of all seven (7) Multi-task Message Tool options. Additionally, several of the examples illustrate the calculations where weekends are not involved, where task bars Start Dates and Finish Dates are within weekends, and where task bars span weekends.
